from around a curve
• When the vehicle is cut in front of
by another vehicle
• When vehicles ahead cannot be
detected due to repeated curves,
road dividers or roadside trees
• When vehicles ahead appear in a
faraway lane on a wide road
• When the lights of vehicles ahead
are not on
● The high beams may be turned off
if a vehicle ahead that is using fog
lights without its headlights turned
on is detected.
● House lights, street lights, traffic
signals, and illuminated billboards
or signs and other reflective
objects may cause the high
beams to change to the low
beams, or the low beams to
remain on.
● The following factors may affect
the amount of time taken for the
high beams to turn on or off:
• The brightness of the headlights,
fog lights, and tail lights of vehi-
cles ahead
• The movement and direction of
vehicles ahead
• When a vehicle ahead only has
operational lights on one side
• When a vehicle ahead is a
two-wheeled vehicle
• The condition of the road (gradi-
ent, curve, condition of the road
surface, etc.)
• The number of passengers and
amount of luggage in the vehicle
● The high beams may turn on or off
unexpectedly.
● Bicycles or similar vehicles may
not be detected.
● In the following situations the sys-
tem may not be able to correctly
detect the surrounding brightness
level. This may cause the low
beams to remain on or the high
beams to flash or dazzle pedestri-
ans or vehicles ahead. In such a
case, it is necessary to manually
switch between the high and low
beams.
